JP4404593B2 - Data printing method and product data register by small printer - Google Patents

Description

  The present invention relates to a data printing method and a merchandise data register capable of reducing costs when a print sheet that can be easily classified and confirmed for each code is created by a small printer.

  The conventional data printing method using a small printer is similar to the product data register using such a method. For example, a printing sheet that can print only a limited number of characters, for example, up to 34 single-byte characters of 12-bit width on one line of 58 mm width. Is used. Therefore, printed products can be easily identified using a method such as line division or paragraph division.

  Such a printed sheet includes, for example, a receipt used for confirming the product purchased at the time of purchase of the product, the number, the price, and the like. Furthermore, there are order sheets for kitchens (hereinafter referred to as kitchen sheets) in restaurants where customer orders are printed and issued to cooks.

  In this product data printing method using a small printer, it is very important to see, for example, a product name on a print sheet, which is useful for reducing mistakes in business processing, while a small printer is printed in a single color. Since it is the mainstream, it has been put to practical use by rearranging the stages for each product, that is, by dividing lines.

  For example, in the receipt 1 shown in FIG. 1, a line is divided for each product, and when there is no unit price of the content of a set product, the line division and the paragraph classification are used together to make the product easy to see. On the other hand, the customer who purchased the product needs to classify and grasp the purchased product for budget management. However, in the case of receipts for a large number of purchased products, the number of rows is large, and in the case of households, for example, there is no product classification such as daily necessities and foods, so it is troublesome and error-prone to transfer products .

  Similarly, for example, in the kitchen sheet 2 shown in FIG. 2, the product name is made easier to see by changing the paragraph for each table number. However, since there is no classification based on ingredients, cooking methods, etc. that can give cooking convenience to the cook, handling is inconvenient.

  That is, since the receipt 1 shown in FIG. 1 or the kitchen sheet 2 shown in FIG. 2 is not classified into products, the classification is relied on manually. Therefore, mistakes are likely to occur.

As an improvement measure, a color printer is used as a small printer, a specific color is set for each product category, and products are printed by color. (See Patent Document 1)
However, even in this proposal, because the limited number of characters is output within the limited width of the receipt or kitchen sheet, even if it is arranged in columns, it may not fit on one line if the product name is long. As a result, the product name must be abbreviated. Further, it is necessary to use an expensive color printer as a printer for sorting products.
Japanese Patent Laid-Open No. 10-143762

  The problem to be solved is that when a product name is printed on a print sheet with a limited width for each line and a part of the classification is changed to a paragraph, a long product name extends over two lines or is omitted. It is difficult to identify or confirm the product name because it must be shaped.

  To solve such a problem, there is a method of distinguishing product names by color information. However, since a color printer and multicolor ink are required, the cost cannot be reduced.

  On the other hand, when short product names are continuous and there are many blanks on the print sheet, there is a need to reduce running costs (management costs) to reduce the number of print lines by continuously printing on one line and saving the print sheet usage. That is.

  In the present invention, a small printer has a means for performing various types of shading printing in a single color, and when printing data on a printing sheet, printing is performed with shading different from adjacent shading for each data based on a predetermined rule. The main feature is to do.

  Thus, in order to facilitate identification of data to be printed, a color printer can be dispensed with because shading is used instead of color information.

  In addition, by printing each data with shading different from the adjacent shading, a plurality of data composing a group can be continuously printed within a line across a plurality of lines, thereby reducing the cost of printing sheets. In addition, it is possible to improve the visibility of data distinction even if continuous printing is performed within one line. The halftone printing may be performed every other line according to a predetermined rule.

  Furthermore, when a small printer is a color printer that prints multiple colors, when printing data, it is possible to use both shading and color information, and also change the ground color in units of lines, etc. In addition, the classification of the data group can further improve the visibility.

  A specific product data register using this method is a product data register for printing a product name and attributes of this product as product data on a print sheet of a limited width by a small printer, and includes a data input unit, a product A data table, an order data table, a processing program storage unit, and a control unit connected thereto are included.

  The small printer prints various shades of monochrome or multicolor, and the data input unit inputs the product name and the attribute of the product as product data. The product data table records and stores in advance product codes, product names, and unit prices of products to be handled. The order data table records and stores a customer number, a product name, a quantity and a total price based on the data input from the data input unit. The processing program storage unit preliminarily sets a shading rule for the print order of the product data, and records and stores a print processing procedure for each type of print sheet.

  The control unit is connected to the small printer, the data input unit, the product data table, the order data table, and the processing program storage unit, and inputs a customer number, a product name code, and a quantity thereof from the data input unit. The order data storage process for reading the product name and unit price with reference to the product data table, calculating the total price and recording and storing it in the order data table, and the customer from the data input unit When receiving a print output request by number, take out the product data corresponding to the corresponding customer number from the order data table, and instruct the fetched product data and the shaded product data according to the predetermined rule A control unit that executes a print command process for instructing the small printer to perform printing. When the small printer by management to print the item data to the print sheet, printed with hooking different nets from the adjacent shaded for each product data based on a predetermined rule.

Data printing process according to a small printer of the present invention has the advantage that since the color printer and multi-color ink corresponding thereto to shaded print for each data Ru can be eliminated, it is a cost saving by using a single-color printer . Also, even if multiple items of data are continuously printed on a single line with a group of products that can be printed continuously on a single line, each data can be shaded differently, reducing the number of lines printed and reducing the length of the printed sheet. Since it can be reduced, there is an advantage that the cost can be further reduced.

  Furthermore, the use of a color printer only saves the printing sheet in terms of cost. However, since multiple colors may be used in the shaded portion, the shaded color and the color can be used together. The ease of classification and visibility are further improved.

  Hereinafter, in the embodiment, the data will be described as product data in a restaurant, but the product data can be applied to other various data.

  First, when printing a product name line by line and changing some classifications into paragraphs on a print sheet with a limited width, the long product name must extend over two lines or be abbreviated. The purpose is to solve the disadvantage that it is difficult to identify or confirm the product name because it is not, and further, it is necessary to use a color printer and multi-color ink to distinguish the product name by color information, and the cost cannot be reduced. When printing product data on a print sheet using a small printer having means for printing various types of shading in a single color, the product data is different from the adjacent shading for each product data based on a predetermined rule. Realized by printing.

  A first embodiment of the present invention will be described with reference to FIG.

  FIG. 3 is a diagram showing a receipt 3 as an example of a receipt created at the time of settlement from a customer's order contents given by a customer number as a table number at a restaurant.

  The order received by the store clerk is recorded as product data including the product name and quantity in correspondence with the table number. In FIG. 3, for example, a set product such as a set meal shown in the receipt 1 of FIG. The names are continuously printed in a single paragraph structure without line breaks with different shades so that each adjacent one can be easily distinguished. Further, in FIG. 3, the subtotal amount, the total amount, and the change amount are shaded to make it easy to see the settlement contents and the number of printed lines can be shortened.

  The paragraph and shaded configurations as described above are created in advance in a printer processing program.

  A second embodiment of the present invention will be described with reference to FIGS. 4 and 5 together.

  FIG. 4 shows an example of a sheet created when a customer requests a table with a customer number at a restaurant and is already input based on a customer's order content as a kitchen sheet (order sheet for kitchen) 4. FIG.

  The order received by the store clerk is recorded as product data including product name and quantity in correspondence with the table number. In FIG. 4, for example, the product name and quantity for each table shown in the kitchen sheet 2 of FIG. In order to be able to easily distinguish each of them, different shades are given and are collectively printed continuously without line breaks.

  FIG. 5 is a diagram illustrating an example in which the type of shading is changed for each line in the case of batch printing over two lines or more. In the case of FIG. 5, when the first row is in the order of four types of shading A, B, C, D, the second row is in the order of shading D, A, B, C, and the shading between adjacent rows Different types.

  That is, in the illustrated kitchen sheet, the product name and its quantity are printed without a line break for each table number, and the length of the print sheet is shortened, but adjacent products are different types of networks. Since the product is hung, it is easy to distinguish the products, and the products for each table number can be recognized together.

  The paragraph and shaded configurations as described above are created in advance in a printer processing program.

  A third embodiment of the present invention will be described with reference to FIG. The third embodiment is a procedure for realizing the first embodiment or the second embodiment.

  That is, FIG. 6 is a flowchart showing a main procedure for printing the receipt 3 in the first embodiment and the kitchen sheet 4 in the second embodiment on the print sheet. Therefore, in this flowchart, a customer number is assigned as a table number at a restaurant, and the store clerk creates product data for the customer's order contents that have already been entered in a kitchen sheet or a receipt when payment is made. An example of a procedure in the register when a print request for the contents of the order is made by a register (hereinafter abbreviated as a register) is shown.

  Orders received by the store clerk are recorded as product data including product names and quantities in correspondence with table numbers. For example, product names with set prices such as set meals described above, and for each table shown on the kitchen sheet Each of the product names is a product that supports batch printing, in which each adjacent item is differently shaded so that it can be easily distinguished and is continuously printed without line breaks.

  That is, when there is an input to the register from the store clerk and an output request to the printer is generated by the table number (procedure S1), the register reads the first product name from the product data corresponding to the table number (procedure S2). If the read product is compatible with batch printing as described above (YES in step S3), for example, a network that is different from the adjacent product on a predetermined basis, such as the shaded order shown in FIG. Multiplication is designated (procedure S4), and batch printing without line feed is requested (procedure S5).

  Next, if there is a next product with the same table number (YES in step S6), the process returns to step S3, and the register repeats the above procedure.

  If step S3 is “NO” and the product is not compatible with batch printing, the register requests sequential printing for each line (step S7) and proceeds to step S6.

  When step S6 is “NO” and there is no next product, printing on a print sheet is executed by the small printer.

  A fourth embodiment of the present invention will be described with reference to FIGS.

  FIG. 7 is a diagram showing an embodiment of a functional block configuration in the register (product data register) of the present invention. In the drawings, only the parts according to the present invention are shown, and some components are omitted due to space limitations even if they are essential in function.

  The illustrated register is provided at, for example, the restaurant entrance described above, and includes a data input unit 11, a small printer 12, a product data storage unit 13, an order data storage unit 14, a processing program storage unit 15, a control unit 16, and data. A display unit 17 is included. These components are connected by a bus and are controlled by the control unit 16 of the processor. That is, the register is an information processing apparatus including a processor, a memory, an input / output device, and the like.

  The data input unit 11 is an input device such as a keyboard and its control unit. When a store clerk receives an order from a customer and inputs a product name, the data input unit 11 converts the product name into a product code, and then sends it to the control unit 16 together with the input quantity. . At that time, the customer number is automatically input by, for example, a sequence number. In the case of a restaurant, the data input unit 11 includes, for example, a portable terminal owned by a store clerk, and inputs an order with the table number as a customer number to a customer who arrives at the table, for example, wirelessly to the control unit 16. It will be. Even in the case of a portable terminal, a conversion table of product names and product codes is usually built in, and even if a store clerk inputs a product name, it is converted into a product code and sent.

  For example, the small printer 12 outputs a receipt to a customer in monochrome printing in response to an instruction from the control unit 16. The small printer 12 may print out a kitchen sheet (order sheet to the kitchen), and the kitchen sheet may be transported to the kitchen. In this embodiment, the kitchen is equipped with a kitchen printer 12k, and the kitchen is wirelessly connected to the kitchen. Data is sent and printed out. At the time of print output, according to an instruction from the control unit 16, the product data such as product name and quantity is shaded and printed. Further, in order to reduce the data amount of the product data handled by the control unit 16, the control unit of the printer has a conversion means for converting the product code into a character code and performs printing. Therefore, in the kitchen printer 12k, when the product code of the set is received, the product name and the quantity constituting the set content are printed out as shown in FIG.

  The merchandise data storage unit 13 has a merchandise data table 21 that records and stores in advance merchandise names, unit prices, and the like for each merchandise code. The order data storage unit 14 takes the input information from the data input unit 11 into consideration and stores the information stored in the product data table 21 under the control of the control unit 16 every time it is received. Record by the total price corresponding to the quantity. The processing program storage unit 15 stores a program executed by the control unit 16 in advance. In the case of a restaurant print output, a receipt processing program 23 and a kitchen sheet processing program 24 are prepared.

  The control unit 16 is a processor, and executes a register function using a processing program stored in the processing program storage unit 15, for example. The operation procedure will be described later with reference to FIGS.

  The data display unit 17 is one of output devices together with the small printer 12, and is also included in a portable terminal of a store clerk having the data input unit 11 described above.

  FIG. 8 is a diagram showing an embodiment of the product data table. Here, the product data table 21 will be described with reference to FIG.

  In the illustrated product data table 21, product codes, product names, unit prices, and the like are recorded in advance. As illustrated, each product code corresponds to a product name and its unit price. In the set product described above, it is assumed that the set product can be determined by the product code, and the product name which is the cooked product is recorded without the product code and the unit price. It is assumed that the product name in the product data table 21 is recorded by a character code printed by the small printer 12 or displayed on the data display unit 18. As described above, the amount of product data handled by the control unit can be reduced by providing conversion tables for converting product names and product codes in both the data input unit and the output unit.

  The order data table 22 does not include a character code corresponding to the product name from the viewpoint of the storage capacity of the storage device, but includes a customer number, product code, quantity, and total price encoded by a combination of numbers, symbols, and numbers. Order data such as is stored. Moreover, although not shown in the drawing, a recording area is provided for whether the kitchen order has been completed for each product code and whether the payment has been completed for each customer number. Therefore, the same product is handled as a separate order after the kitchen order.

  The receipt processing program 23 is used, for example, when the control unit 16 executes the output of the receipt 3 in FIG. 3, and the kitchen processing program 24, for example, outputs the kitchen sheet 4 in FIG. Used when the control unit 16 executes. Further, for receipt, a process for batching the same product after the kitchen order is included as a processing program of the control unit 16.

  Next, referring to FIG. 7 together with FIG. 9, an embodiment of a procedure showing an overall flow when data is input from the data input unit 11 in the register (product data register) shown in FIG. 7 will be described. Will be explained.

  First, in the data input unit 11, the register receives a table number input from a store clerk who has received an order from a customer at a table (table), a product code converted from a product name, and its quantity (step S11). This is sent to the control unit 16. The control unit 16 refers to the product data table 21 by the product code (step S12), and reads the unit price corresponding to the product code. Next, the control unit 16 records the received product code, its quantity, and the price calculated from the unit price in the order data table 22 as product order data, using the table number as the customer number (step S13).

  At this time, if the data input unit 11 has received the next input in step S11 (YES in step S14), the control unit 16 takes in the input reception data and repeats the procedure from step S12. When the above step S14 is “NO” and “no next input is accepted”, the control unit 16 uses the kitchen processing program 24 described later with reference to FIG. Print output is performed from 12k (step S20).

  At this time, if the data input unit 11 has received the next input in step S11 (YES in step S15), the control unit 16 takes in the input reception data and repeats the procedure from step S12. When the above step S15 is “NO” and “no next input is accepted”, the control unit 16 waits for the receipt of the “settlement request” from the data input unit 11 by the store clerk (step S16). In accordance with a receipt processing program 23, which will be described later, a receipt based on the order data is printed out from the small printer 12 (step S30).

  Next, with reference to FIG. 10, one embodiment of the details of the kitchen sheet printout procedure S20 in FIG. 9 according to the kitchen processing program 24 will be described. As described above, it is assumed that the kitchen printer 12k is installed in the kitchen and a kitchen sheet is printed out from the kitchen printer 12k when an order is received.

  The control unit 16 in the register determines that a kitchen sheet print request has been generated when the next order input is not received from the data input unit 11 at the end of the step S13 in which the order data is recorded and the step S14 is “NO”. Then, one product code is read from the order data table 22 with the corresponding table number as the customer number (step S21).

  If the corresponding product is a set product (YES in step S22) from the read product code, the control unit 16 reads the product name of the set content corresponding to the set product from the product data table 21, and the printer data temporary memory 17 A batch print in one paragraph is designated and recorded (step S23).

  Subsequently, the control unit 16 checks the same table number in the order data table 22, and if there is next product data (YES in step S24), the control unit 16 returns to step S21 and repeats the above procedure.

  If the product read out in the above step S22 is “NO” and is not a set product, the control unit 16 designates and records a batch print successively in the same paragraph together with other products ordered simultaneously with the same table number. (Procedure S25) and continue to the procedure S24.

  When the above step S24 is “NO” and there is no next product data in the same table number in the order data table 22, the control unit 16 uses different networks for the adjacent product data according to a rule predetermined in the printer data temporary memory 17. Recording is performed by specifying the multiplication (step S26). Next, the control unit 16 examines the order data table 22, and if there is a next table number (YES in step S27), the control unit 16 returns to the above step S22 and repeats the procedure from reading the product data.

  If this step S27 is “NO” and there is no next table number, the control unit 16 sends the kitchen sheet data in the printer data temporary memory 17 to the kitchen printer 12k for each table number, and instructs output. Therefore, for example, as shown in FIG. 4, the kitchen printer 12k creates a kitchen sheet and prints it out (step S28).

  In the above description, the inner surfaces for all the recorded table numbers are collectively printed out sequentially, but a procedure of sequentially printing out each table number may be used.

  Next, with reference to FIG. 11, an embodiment of the details of the receipt printout procedure S30 in FIG. 9 according to the receipt processing program 23 will be described. The small printer 12 is provided in a register at the entrance of a restaurant, and a receipt is printed out from the small printer 12 at the time of payment.

  The control unit 16 in the register determines that the receipt request output from the data input unit 11 has been received in step S16, and generates one receipt code from the order data table 22 with the corresponding table number as the customer number. Is read (step S31).

  If the corresponding product is a set product (YES in step S32) from the read product code, the control unit 16 reads the product name of the set content corresponding to the set product from the product data table 21, and temporarily stores the printer data memory 17. A batch print in one paragraph is designated and recorded (step S33). Next, the control unit 16 designates different shades for adjacent product data according to a predetermined rule, and records them in the printer data temporary memory 17 (step S34).

  Subsequently, the control unit 16 checks the same customer number in the order data table 22, and if there is next product data (YES in step S35), the control unit 16 returns to step S31 and repeats the above procedure.

  If the product code read out in the above step S32 is “NO” and the product code is not a set product, the control unit 16 changes the paragraph with the other product ordered at the same time with the same customer number, and specifies the print to be sequentially printed on the next line. To record (procedure S36), and then continue to the above-described procedure S35.

  When the above step S35 is “NO” and there is no next product data for the same customer number in the order data table 22, the control unit 16 sends the receipt data in the printer data temporary memory 17 to the small printer 12 for each customer number. To output. Therefore, for example, the small printer 12 creates a receipt as shown in FIG. 3 and prints it out (step S37).

  In the above description, the customer number is a table number. However, different customers may be present in the same table, and the customer data and the table number are used in the order data table. For example, a customer number is a number based on a date and an acceptance order.

  As described above, since the adjacent product data is shaded in different single colors when printing, it is easy to view the receipt or the kitchen sheet without increasing the cost with a printer, printer ink, printing sheet, etc. Can be improved.

  A receipt 5 that is different from that described above will be described with reference to FIG.

  In the fifth embodiment shown in FIG. 12, the receipt 5 is shaded for each column in which the product name and the price are combined. In this case, receipts that are easy to see are formed by changing the types of adjacent shades.

  A receipt 6 that is different from that described above will be described with reference to FIG. 13 for Embodiment 6 of the present invention.

  In Example 6 shown in FIG. 13, a receipt that is easy to see is created by simply shading every other line in the receipt 6.

[Other embodiments]
In the embodiment described above, a single-color small printer is used. However, using a color printer capable of multicolor printing, it is possible to print the shaded portions in colors corresponding to each type.

  In addition, by using color as a complementary color for shading, or using a combination of these in combination, it is possible to change the ground color in units of lines when printing data. Group classification can also improve visibility.

  In other words, when multicolor printing is used with a color printer and used in combination with halftone printing, the cost of the apparatus and ink is increased, but the identification is easy, that is, the visibility is outstanding, and the ease of viewing and the amount of printed sheets are reduced. Cost savings have the advantage of far exceeding the cost of making a small printer a color printer.

  According to the data printing method and the merchandise data register by the small printer according to the present invention, it is possible to print on a print sheet with a small printer capable of halftone printing of a single color and a plurality of types of patterns. Cost can be reduced easily.

  On the other hand, among the data that was conventionally divided into paragraphs with line breaks, multiple data that can form one paragraph over multiple lines without line breaks are printed continuously even within one line, and different types of patterns are used for adjacent data By using half-tone printing, it is possible to reduce the amount of printed sheets used and to reduce running costs.

  For this reason, by using a color printer, it is possible to identify with multiple colors instead of shading, and auxiliary coloring by combining shading and color can realize easier viewing. Even if printing is made easier to see by dividing it, a single paragraph is formed over multiple lines without line breaks, and even if a large number of data is printed continuously over a number of lines within a line, the individual data can be easily identified. Applicable to necessary and indispensable uses.

  Therefore, the data printing method according to the present invention is not limited to product data, and is not limited to a narrow width printing sheet, and for each data, it is possible to arrange the shading, color, and combinations of these without being easy to see, It can be applied to list printing of various data by a general-purpose printer.
